摘  要:
采用机制法对辽宁省坡耕地的玉米、高粱、大豆三种主要作物生产潜力进行了估算,并分析了影响该地区现实生产力的主导因子。研究结果表明,坡耕地上作物的生产潜力玉米为6 935 kg/hm2,高粱为5 920 kg/hm2,大豆为5 627 kg/hm2。在可控环境因子中,坡度对作物生产潜力的影响最大,其次是温度和水分因子。

摘  要:
The potential grain productivity of corn,broomcorn and soybean is respectively calculated by using mechanism method,and the vital factor that affects practical grain productivity of hilly fields in Liaoning province is analyzed.It is surveyed that in this region the potential productivity of corn is 6 935 kg/hm~2;the potential productivity of broomcorn is 5 920 kg/hm~2;the potential productivity of soybean is(5 627 kg/hm~2).At the same time,slope is the greatest factor that can be controlled for impacting on potential productivity,and then temperature and soil water are the second ones.
